The Edge 500 attaches easily to the stem or handlebars of your bike with its low-profile bike mount. The Edge attaches easily to the mount with a simple quarter-turn. When you're ready to ride, just power on your Edge, acquire GPS satellites and go. Edge 500 features a high-sensitivity GPS receiver with HotFix satellite prediction to calculate your position faster.

All Edge 500 versions work with third-party ANT+-enabled power meters to display your power output in watts as you ride. This valuable data shows you how hard you're working, regardless of conditions affecting your ride, so you can train smarter. Some versions also ship with a digital heart rate monitor and speed/cadence sensor.

Other helpful training features include a Courses feature, which helps you compare successive rides over the same route, as well as Auto Pause, Auto Lap and temperature readings. Edge also alerts you if you're moving but the timer is not running.

Track Your Heart Rate

When paired with a Garmin heart rate monitor, Edge 500 tracks heart beats per minute and uses your heart rate for advanced calorie computation, so you know how many calories you're burning. Train in a certain heart-rate zone to improve your fitness level or compare your pace and heart rate to past performance over the same ride.

Analyze Your Ride

Once your ride's done, connect Edge 500 to your computer with the included USB cable to analyze your performance. With a simple click, you can join a worldwide network of cyclists and outdoor enthusiasts through Garmin Connect, a one-stop site for data analysis and sharing.
